or apartment, and synchronously robbing the air of moisture, so that moisture is adequate ly eliminated'from the air that is permitted to pass under pressure into the enclosure or apartment.

Other objects and practicable advantages of the invention will be more fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

igure 1 is a vertical sectional view illustrative of the preferred embodiment of my invention. J p

Figure 2 is an enlarged horizontal section taken on the plane indicated by the line 22 of Figure 1, looking-downward.

Figure 3 is a detail verticalsec'tlon taken on'the plane indicated by the line 3-3 of Figure 1, looking toward the right, and illustrating the gutter arrangementcomprised in my improvement.

Figure 4-'s an enlarged fragmentary section illustrating the adjustable connection for the crown bafiie member of the improvement.

Figure 5 is a detail erspective of one of the battles disposed in t e oasingbody of the improvement.

Similar numerals of reference 1 designate corresponding parts in all the views of the drawings.

I show in Figure 1 a floor 1 which may be that of an apartment in a building, a car or any other enclosure to which my improvement is applicable.

The floor 1 is provided with an opening 2, and in said opemn 2 is arranged the flanged open upper end 0 the casing body 3 of my improvement. The said casing body 3 is provided with a tapered lower end 4, and in bottom 4 is a pipe 5 design connection with the central portion of the ed to carry ofi' moisture in any'suitable point of discharge.

Disposed laterally to the casing body 3 is a conduit 6, through which air is forced into the lower portion of the casing body 3.

The end of the conduit 6' within the casing body 3 is shaped to form a gutter 7 with discharge terminals 8, Figure 3,'disposed over the tapered bottom 4 of the casing body 3. This provision is advantageous inasmuch as moisture collected from the inflowing air will find its way into the gutter 7 and will be conducted by the said gutter 7 to the taperedbottom 4 from which it will pass through the pipe 5.

Arranged in staggered relation in the casing body 3 are baflies 9, of obtuse angle form, Figures 1 and 5, and varied in size. The said bafiles 9 are arranged with their apices 10' downwardly, and are generally inclined as brought out in Figure 1, and each bafile 9 is fixed to the wall of the casing body 3 and is provided adjacent to said wall with a drain aperture 11, Figures 1 and 5, said aperture 11 being preferably afforded by notching of the end of thebafile continuous to the casing wall, as shown. a

Disposed diametricall across the upper portion of the casing ha y 3 is a bar 12 with a central enlarged portion 13 in which is a threaded bore 14, Figure 4.

At 15 is the crown baflle of the improvement. The perimeter of the said bafile 15 is preferably shaped as indicated by 16 to conform to the flared discharge end of the casing body 3, and so that said perimeter 16 will serve in conjunction with the flared upper end of the casing body 3' to distribute air radially from the upper end of the casing body 3 to various parts ofthe enclosure or a artment in which the crown baflie 15 is disposed. The under side of the crown bafile 15 1s concaveas designated by 17, in order to catch moisture and precipitate the same back to the side portion of the casing body 3.

Appropriately fixed to and extending through the crown bafiie 15 is a stem 18 with an appropriate handle 19 at its upper end. The said stem is threaded as designated by 20 and is arranged in the threaded bore of the bar 12, and consequently the crown bafiie 15 may be expeditiously and easily adjusted,

and may be positioned at various points above novel ventilator or air distributor and moisture eliminator, air under pressure is appropriately supplied through the conduit 6, and when such air enters the casing body 3 it strikes the lower bafiie 9 and is diverted 1. against the next upper and opposite battle 9,

and so on until it reaches the upper end of the casing body 3., At this latter point the air brings up against the crown bafile 15 with the result that the air is discharged from the upper portion of the ventilator radially and is evenly distributed throughout the apartment or other enclosure. The downwardly disposed flange 25 of the crown baffle 15 prevents moisture from escaping with the air and causes the moisture to drip back into the casing body 3. lhe air under pressure bringing up against the under side of the baflies 9 will be robbed of excess moisture, and by virtue of the obtuse angle form of the bafiies 9 the bafiies afiord large surfaces and at the same time promote the drainage of moisture downward against the inner side of the casing body 8. It will also be appreciated that the inclination of the .baffles 9 is such that the air passing upwardly in the casing body 3 will strike against the concavity in the crown bafile 15 which crown battle will obviously assist in robbing the air of moisture. Such moisture as gathers at the upper side of the battle 9 will be drained to the apertures 11, and will pass down the inner side of the casing body 3 to the tapered bottom 4 by which the moisture will expeditiously be conducted to the drain pipe 5.

The discharge end of the conduit 6 is disposed in the casing body 3, but this will not interfere with the downward passage of moisture to the drain pipe 5 inasmuch as the gutter 7 will receive a portion of the descending moisture and will facilitate the downward passage of the same. Manifestly all the moisture passes down at'thc side of the casing body 3 and hence there is no liability of moisture dripping across the discharge end of the air conduit 6 which is an important advantage.

By virtue of the connection described complementary to the crown bafiie 15 said bafile 15 may be entirely closed, or may be opened and maintained in open position at various points above the discharge end of the casing body 3.

Obviously any desired number of my improved devices may be used in conjunction with a single room or other enclosure, and in the discretion of a. person in authority some of the crown baffles may be opened to a greater extent than others, "or someof the crown bafiies may be left closed, while others are open, according to the condition to be met with respect to the adequate supply of fresh, dry air to the room or other enclosure.

" In addition to the practical advantages ascribed to my improvement, it will be apparent that the improvement is simple and inexpensive in construction, is well adapted to withstand the usage to which devices of corresponding character are ordinarily subjected, and is entirely free of delicate parts suchlas are likely to get out of order after a short period of use.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the said embodiment which is preferred. I do not desire, however, to be understood as limiting myself to the precise construction and relative arrangement of parts as disclosed, my invention being defined by my appended claims within the scope of which modifications may be made without departure from my invention.
